About LLMStack

LLMStack is a no-code platform and open-source framework for building generative AI apps, chatbots, and multi-agent workflows. It enables users to import and preprocess data (CSV, PDF, DOCX, PPTX, text, website content, Notion, Google Drive, etc.), vectorize it, and connect that data to chained LLMs and multi-agent pipelines. The platform provides a web UI and CLI to design, orchestrate, and deploy agents and workflows, plus integrations to major LLM providers and an out-of-the-box vector database, enabling rapid prototyping and deployment of data-driven conversational and automation applications.
